A shaft 11 extends through the bore of the bushing 4 and the opening 3 into the tank 1 and is freely rotatable. A rocker arm 12 extends4 Within the tank 1 substantially at right angles to the shaft 11 at the inner end of the latter and comprises a section 13 which is by preference integral with the shaft 11 at the inner ,end of the latterand a section having a threaded boreV 15 engaged with threads 16y on the outer endportion ot the section 13 whereby the rocker arm .12 is ade, instable in looeth- A nut '17 on the threaded end Portion 16 of. the. ssotion `13 may be Vacljusted to hold the sections 13` and -1 4 adr instal Connected toe-.other relatonl The section lil of the lrocker arm has a laterally turned end portion 18 which; carries a float 1 9.

The, verticslfshft 'se extends fr the upper end of" the tiihuliar housing 27V and is threaded adjacent to its upper end. An

`'indicator ring 38 having spaced apart indicia on'its periphery as indicated at 39 is formed Y vertical shaft 34 extends. Y! The indicator ring 38 is secured to the'vertical'shaftll to rotate with the latter vthrough the agency of a p air of clamping nuts 42. Respectlve clampmg llov nuts 42 are in threaded engagement with the`A upper end portion of the shaft 34 and one oi' these nuts is disposed below the cross piece 40 while the other nut 42 is disposed on the threaded end portion of the shaft 34 above the cross piece 40 toclamp the latter against the llirst nut 42. y

The tubular housing 2O may be of such lengt-l1 and disposed in such relation to the body of the automobile 2 that the upper end portion of the tubular housing 27 will be received within a cylindrical casing 43 which is supported adjacentto one of its ends. in an opening 4-4-in the instrument board 45 of the automobile The-indicator ring 38 WillA be disposed within the casing43 which may be provided with a slot"46'through which the upper end'portionof the housing 27 may extend.- Theslot46 extends `from one end of theicasing-43 for part of the length of said casing so that the'casing 43 canbe removed from' the opening 44 ofthe instrument board if' desired without there beingany necessity of removing the tubular housing or any of theremaining parts of the device from the positions shown in Figure 2. The casing 43 has a transparent closure 47 received within the'inner end thereof. An opaque backing plate or closure 48 which is located Within the casing'43 betweenthe indicator ring 38 and transparent closure 47 has an opening 49 through which the-indicia on the indicator ring 38 may beseen.

i From the foregoing description of the various parts of the device', the operation thereof will bel readily understood. The shaft ll constitutes a .drive shaft which will be rocked as the float 19fis moved within the tank l in accordance with the rise and fall of a liquid Within the tank. The shaft ll will operate the vertical or driven shaft 34 and the indi- 'catorring 38fvvillnbeprotated with the shaft 34 to present the indicia on the ring 38 successively to view through the opening 49.

The indicia 39 indicate various quantities or depths of liquid AWithin the tank, as for instance'the indicia may comprise the letters F,

etely empty. The rocker arm l2 through the opening when the tank is empty.

The gear 30 is considerably larger than the gear 32, the' ratio preferably being 2` to 1.

vWhile the device is designed primarilyy for itl may be applied to tanks other than those with which automobiles are equipped without., departing from the spirit and scope of the invention. f

Obviously, my invention is susceptible "ot embodiment in forms other than that illus` trated in the accompanying drawings and I therefore consider as my own all modiiications and adaptations of the form of the device'herein described which fairly fall within thescope of the appended claims.

Having thus described the invention, what is claimed is: f

l. In a liquid gauge, ak tubular housing to be supported vertically adjacent the instrunient board of an automobile, a shaft journalled in the tubular housing with one end projecting above lthe same, a rotatableindicating element carried by the projecting end of the shaft, and a housing insertable through van opening in the instrument board to house the indicating element and havingone `end open vand having its Wall provided with a jlongitudinal slot embracing the tubular housing, a si ht glass arranged within the other end of t e housing. 1

2. In combinationV a support having an vopening therein, a tubular housing supported vertically to one side of the support with one receiving the rotatable indicating e ement, and

provided with a longitudinal slot receiving the upper end ofthe tubular housing and permitting longitudinal movement of the casing to and from the opening. f
